How to Install XTENDED XT Android 13 ROM on OnePlus 7T/Pro

Before starting with the process, make sure to take a complete device backup beforehand. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.

STEP 1: Install Android SDK

First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform-tools folder, which will be used throughout this guide.

STEP 2: Enable USB Debugging and OEM Unlocking

Next up, you will have to enable USB Debugging and OEM Unlocking on your device. The former will make your device recognizable by the PC in ADB mode. This will then allow you to boot your device to Fastboot Mode. On the other hand, OEM Unlocking is required to carry out the bootloader unlocking process.

So head over to Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging and OEM Unlocking.

STEP 3: Unlock Bootloader

Next up, you will also have to unlock the device’s bootloader. Do keep in mind that doing so will wipe off all the data from your device and could nullify its warranty as well. So if that’s all well and good, then please refer to our detailed guide on How to Unlock the Bootloader of any Android Device.

STEP 4: Download XTENDED XT ROM & Recovery for OnePlus 7T/7T Pro

Now, get hold of the XTENDED XT ROM and Recovery files from below [GApps included in the ROM]:

OnePlus 7T [hotdogb]: ROM | Recovery | Copy Partitions ZIP
OnePlus 7T Pro [hotdog]: ROM | Recovery | Copy Partitions ZIP

The ROM file will be present as a ZIP whereas the recovery will be an IMG file.
Once both files have been downloaded, transfer them to the platform tools folder on your PC.
Next up, rename the recovery file to recovery, so that the complete name becomes recovery.img.
Likewise, rename the ROM file to rom, so that the complete name becomes rom.zip.

STEP 5: Boot to Fastboot Mode

Connect your device to the PC via a USB cable. Make sure USB Debugging is enabled.
Then head over to the platform-tools folder, type in CMD in the address bar, and hit Enter. This will launch the Command Prompt.
After that, type in the following command in the CMD window to boot your device to Fastboot Mode
```
adb reboot bootloader
```
To verify the Fastboot connection, type in the below command and you should get back the device ID.

STEP 6: Flash XTENDED XT Recovery

You will now have to flash the XTENDED XT recovery onto the recovery partition of your device. So execute the below command for the same:
```
fastboot flash recovery recovery.img
```
Once the flashing is complete, use the hardware keys to bring up the Recovery menu and hit the Power key to confirm it.
Your device will now boot to the XTENDED XT Recovery [it is a touch-based recovery, so you could use it without interacting with the hardware keys].

STEP 7: Copy Content of Slot A to Slot B

In order to maintain consistency of the firmware versions between the two partitions on your device, we will now be copying all the contents of Slot A to Slot B.

Transfer the Copy Partitions ZIP to the platform tools folder on your PC. Likewise, rename it to cp.zip.
Then on the XTENDED XT recovery, select Apply Update > Apply from ADB.
After that, open CMD inside the platform-tools folder and execute the below command
```
adb sideload cp.zip
```
Once flashed, go to Reboot and select Recovery. Your device will reboot to XTENDED XT Recovery.

STEP 8: Factory Reset Device

From the XTENDED XT Recovery, go to Factory Reset.
Then select Format Data/Factory Reset > Format Data.
Your device will now undergo a reset.
Once done, you shall get the “Data wipe complete” message.

STEP 9: Install XTENDED XT ROM on OnePlus 7T/Pro

From the XTENDED XT Recovery, go to Apply Update > Apply from ADB.
Then head over to the platform-tools folder, type in CMD in the address bar, and hit Enter.
This will launch the Command Prompt. So type in the below command to flash the ROM file via Sideload:
```
adb sideload rom.zip
```
The process will now begin and once done, you shall get the Total xfer: 1.00x message [Got an error? See FAQ below].
